How to help the visually impaired? Need help

[Stayin100]

I know a guy that wants to get into a droid phone, but theres one hiccup. He was born without any corneas. He currently has a LG Dare, an all touch screen phone, and a rather small one compared to todays smart phones. He's ready for a new upgrade and is interested in the droid's. I told him I'd do some research into how I could possibly assist him with making the phone more accessible to him. The Dare has a setting for high contrast, making all the backgrounds black and the text white. I need to find some sort of app or launcher/theme that will do this for him on a droid. He uses voice to text on his current device and I showed him how he could use voice input for mostly everything on the droid as well. Any ideas?
